Axillary lymph node dissection (ALND) in patients with breast cancer has potential side effects, including upper-limb lymphedema. Axillary reverse mapping (ARM) is a technique that enables discrimination of the lymphatic drainage of the upper limb in the axillary lymph node basin from that of the breast. We aimed to evaluate ARM node identification by near-infrared (NIR) fluorescence imaging during total mastectomy with ALND and then to analyze potential predictive factors of ARM node involvement.

The study enrolled 119 patients diagnosed with invasive breast cancer with an indication for ALND. NIR imaging using indocyanine green dye was performed in 109 patients during standard ALND to identify ARM nodes and their corresponding lymphatic ducts.

94.5% of patients had ARM nodes identified (95%CI=[88.4-98.0]). The ARM nodes were localized in zone D in 63.4% of cases. Metastatic axillary lymph nodes were found in 55% in the whole cohort, and 19.4% also had metastasis in ARM nodes. Two patients had metastatic ARM nodes but not in the remaining axillary lymph nodes. No serious adverse events were observed. Only the amount of mitosis was significantly associated with ARM node metastasis.

ARM by NIR fluorescence imaging could be a reliable technique to identify ARM nodes in real-time when ALND is performed. The clinical data compared with ARM node histological diagnosis showed only the amount of mitosis in the diagnostic biopsy is a potential predictive factor of ARM node involvement.

NCT02994225.The aim of this systematic review was to determine the prevalence of the canalis sinuosus (CS) and accessory canals of the canalis sinuosus (ACCS) as identified on cone beam computed tomography (CBCT). Online searches were conducted in the MEDLINE (via PubMed), Scopus, LILACS, Cochrane CENTRAL, Web of Science, and SIGLE (via OpenGrey) databases. Primary studies that determined the prevalence of canalis sinuosus and/or its anatomical variations using CBCT were included. The risk of bias assessment was performed using the AQUA tool. The quality effects model using double arcsine transformation was used for the meta-analysis of prevalence. Heterogeneity, publication bias, and sensitivity analyses were performed. Of 3237 initial results, 17 papers were included for systematic review. The meta-analysis comprising 1994 patients showed a pooled prevalence of CS of 0.80 (95% confidence interval (CI) 0.51-0.99; P = 0.001; I2 = 99%). Publication bias analysis revealed minor asymmetry (LFK index 1.84). The meta-analysis of 4605 patients showed a pooled prevalence of ACCS of 0.54 (95% CI 0.38-0.69; P = 0.001; I2 = 99%). The sensitivity analysis showed a pooled prevalence of ACCS of 0.53 (95% CI 0.32-0.74; P = 0.001; I2 = 99%) for studies with ≥ 1000 patients and 0.55 (95% CI 0.33-0.76; P = 0.001; I2 = 98%) for studies with less then 1000 patients. Canalis sinuosus showed a pooled prevalence of 0.80 and ACCS showed a pooled prevalence of 0.54; hence both should be considered as anatomical structures, which means that they are present in most people. Surgeons must be aware of the CS and ACCS on CBCT analysis during pre-surgical planning. PROSPERO REGISTRATION NUMBER CRD42020154195.Implant placement in the posterior maxilla is not an easy procedure, not only due to the low quality of bone, but also the physiological pneumatization, which decreases the remaining bone height to the maxillary sinus. Sinus lifting is an alternative for implant placement in these cases. The aim of this study was to radiographically compare the effect of Densah densifying burs versus osteotome in transcrestal sinus lifting. Twelve patients with missing premolars or molars and limited residual bone height were enrolled in the study and divided equally (by coin toss) into two groups group A underwent densifying bur sinus lifting and group B underwent osteotome sinus lifting. Follow-up was performed over 6 months. Bone density (measured around the implant and at the implant apex) and bone height gain (measured using three reference points across the implant length) were measured using OnDemand 3D software. Bone density around the implant was found to be significantly higher for the densifying burs (P = 0.010); however, no significant difference in bone height gain (P = 0.985) or apical bone density (P = 0.337) was detected between the two groups. Densifying burs significantly improved bone density around dental implants, but did not prove to provide a significantly higher bone height gain or apical density compared to osteotomes in graftless internal sinus lifting.

The impact of combinations of yogic practices on bronchial asthma have been studied. Such yoga modules tend to be too lengthy for comfortable practice long-term, giving high dropouts. Returning to conventional medicine despite improvement is common. This study tested a shorter, easier yoga routine to improve asthma condition.

Sixty young adults aged 18-30 years diagnosed with bronchial asthma of mild to moderate severity were randomly assigned to the Yoga Group, add-on yoga therapy and continuing prescribed medication, or the Control Group, continuing prescribed medication only. Measurements on days 0 and 90, included Asthma Quality of Life Questionnaire, Hamilton Anxiety Rating Scale, Beck's Depression Inventory and Pulmonary Function Tests. The yoga therapy module, practised 30 mins daily, included four kinds of yoga breathing practices, and ended with guided relaxation.

All Asthma Quality of Life subdomains improved greatly for the Yoga Group as did Hamilton Anxiety and Becks Depression Inventory scores, t statistics were high (40 -75), all p<.0001. Pulmonary Function also improved greatly in all variables, with smaller t statistics from 2 to 14.The Control Group showed some small improvements. read more Differences observed in scores were highly significant, with large effect sizes. Finally, no dropouts occurred.

Zero dropouts represents an unprecedented result. The yoga module was completely acceptable to participants, Yoga Group improvements were highly significant. The study indicates that the new yoga module effectively improves quality of life, levels of anxiety, depression and pulmonary function in young adults with above-stated bronchial asthma.

It consists of distended tubules that may have either intratubular seminoma or intratubular embryonal carcinoma cells. Many invasive non-seminomatous tumors contain a mixture of tumor types, which are reviewed here. Morphology, aided by a panel of immunostains, can determine the presence and percent of embryonal carcinoma, yolk sac tumor, choriocarcinoma, or teratoma in such tumors. Use of immunostains, required for diagnosis in perhaps 25% of testicular neoplasms, is reviewed. Changes of classification in the AJCC (8th edition) in 2016 are discussed, including the partitioning of two tumor types the central role of chromosome 12p amplification allows both teratoma and yolk sac tumor to be divided into prepubertal types (lacking amplification) and post-pubertal types. Occasionally, sex cord-stromal tumors, hematolymphoid tumors, or epididymal adenomatoid tumors enter the differential diagnosis of germ cell neoplasms.Previous meta-analyses have shown that the hospital admission of older patients in acute geriatric units (AGU) compared to admission to other conventional units, significantly reduced the risk of functional deterioration during hospitalization, increasing the possibility of returning home, with an added reduction in cost of hospitalization. A new meta-analysis on the subject has recently been published in Age and Aging, which adds six new studies to the five clinical trials analyzed in previous meta-analyses. This article analyzes the results of this new meta-analysis, delving into the characteristics of the new studies included and making some considerations on the implications for care in the future development of AGU.

In addition to melanocytic hyperfunction, changes are observed in the upper dermis of melasma, and fibroblasts play a central role in collagen synthesis and pigmentation induction.

To explore the morphology, growth rate, and gene expression profile of fibroblasts from the skin with melasma in comparison to fibroblasts from the adjacent healthy skin.

Ten women with facial melasma were biopsied (lesion and adjacent healthy skin), and the fragments were processed for fibroblast culture. Samples from five participants were seeded to evaluate growth (days 2, 5 and 8) and senescence (SA-β-gal) curves. The samples from the other participants were submitted to real-time PCR to comparatively evaluation of the expression of 39 genes.

Cultured fibroblasts from melasma skin were morphologically less fusiform in appearance and on average a 34% (95% CI 4%‒63%) greater proportion of cells labeled with SA-β-gal than the fibroblasts from the adjacent skin. The cell growth rate was lower for the melasma samples after eight days (p < 0.01). TheWNT3A, EDN3, ESR2, PTG2, MMP1, and SOD2 genes were up-regulated, whereas the COL4A1, CSF2, DKK3, COL7A1, TIMP4, CCL2, and CDH11 genes were down-regulated in melasma skin fibroblasts when compared to the ones from adjacent healthy skin.

Small sample size; absence of functional tests.

Fibroblasts from the skin with melasma showed a lower growth rate, less fusiform morphology and greater accumulation of SA-β-gal than those from adjacent photo exposed skin. Moreover, their gene expression profile comprised factors that may contribute to upper dermis damage and sustained melanogenesis.

Whilst this has been welcomed within the palliative care field and seen as a route to greater recognition, we focus here on a more critical perspective that challenge the effectiveness of a 'policy turn' in palliative care. Applying Bacchi's "What's the Problem Represented to Be?" (WPR) framework to data from a systematic search, we address the research question, "in what ways has 'policy' been articulated in palliative care literature?". The paper describes the construction of 'the problem' context and reflects critically on the robustness and pragmatic utility of such representations. In particular, we identify five elements as prominent and problematic (1) a lack of empirical evidence that connects policy to practice; (2) the dominance of 'Global North' approaches; (3) the use of a policy narrative based on 'catastrophe' in justifying the need for palliative care; (4) the use of idealistic and aspirational 'calls to action'; and (5) a disengaged and antagonistic orientation to existing health systems.
